Avoid duplicate row issues in biblio.extract_located_uris

As there is currently no unique constraint on the non-ID columns of
asset.uri, ensure that we only select a single ID from the tables until
we dedupe the tables. Use an ORDER BY to grab the matching row with the
lowest ID so we can clear out the rows with higher IDs.
